This is a cooling mat that can be used with baby carriers and strollers. The part for inserting ice packs is removable. When not in use, it can be rolled up and stored in the included case. *An ice pack is also included, but it shows signs of use (photos 5 and 6). Please let me know if you don't need it. I will discount it by 50 yen (for the ice pack). The included case has some stains (photo 8). Please understand that this is a used item before considering a purchase. For shipping purposes, the cooling mat will be packaged separately from the case. Thank you for looking.
